Re: axen Ethernet device errors on both USB3.0 and USB2.0 ports

Denis Lapshin-2
Hello,

After patching axen5-63.diff and xhci63.diff axen(4) driver hangs
randomly (LED stopped blinking and down on the Axen device). A system is
hang completely without any related error records present in dmesg.

Why axen(4) 16kB buffer size as in original code affected on system
stability?

I have to rolled back to axen3.diff with set_config part to have it
works on xhci(4). Axen adapter works stable on xhci(4), but generates an
error on other USB2 ports like in previous posts:

axen0: rxeof: too short transfer
axen0: rxeof: too short transfer
axen0: rxeof: too short transfer
axen0: rxeof: too short transfer
axen0: usb drrors on rx: IOERROR

I've just applied both axen5-63.diff and xchi63.diff and reconnected
axen to USB2 port. It works about 30min. Afterwards OBSD 6.3 hangs
completely without any kernel errors provided.

Going to retest it one more time.

Here is dmesg where axen(4) hangs:
